Thanks. Using your script, what I can't do is to include a heading inside 
the fenced div, can't I? The reason is that I need solution to be presented 
in a different slide. I had just found a kind of solution, using heading 
identifiers (although when compiling to beamer it spits a warning (as 
several sections share the same identifier):

local looking_at_section = false
local lvl = 0
local remove = {}  -- delete line if 'remove' array not needed

function Block (elem)
  if elem.t == "Header" then
    -- if elem.classes:includes('remove',1) then

    if elem.identifier == 'answer' then
      looking_at_section = true
      lvl = elem.
level
    else

      looking_at_section = looking_at_section and elem.level >
lvl
    end
  end
  if looking_at_section then
    remove[#remove + 1] = elem  -- delete line if 'remove' array not needed
    return {}
  end
end
